While a little off topic I had an interesting situation a few weeks back transiting through SIN from CGK so first leg on Jetstar under QF flight No then onto QF72 as WP in J the F lounge closed and the J open although refused entry as it was full due to a delayed QF2. So even though WP traveling in J told no entry and to wait a few hours until the F lounge opened. Reasonable maybe as it was outside the normal hours of the lounge although no other Oneworld lounges open. At least plenty of options in the airport to fill in the couple of hours although still felt disappointed in the outcome.
